It's a left hand thread. Crank to the right.
first you should release the belt tension pully and remove the belt. Then the idler pully has a bolt through the center remove the bolt and the pully should come off.
The water pump and timing components should be replaced at intervals specified by manufacturer and you may replace just the idler pulley.
Most technicians refer to the idler pully for the timing belt as just idler.

My guess would be the camshaft sensor, or idler pully, or water pump, or your compressor
It is called an Idler pully and is not there to tension the belt.
a 92 Silverado 350 uses a single serpentine belt that is tensioned by a spring loaded idler pully. When facing the engine from the front of the vehicle, the tensioner is near the top of the engine slightly left of center. Using a breaker-bar and socket, remove tension from the idler pully and simultaneously slide the serpentine belt off one of the other pulleys. I usually pick the alternator pully since it's so close. Note the path of the old belt and make certain that the new belt is installed along the identical path. Put the belt on all pullies, including the idler pully and hold it with slight tension near the alternator pully, then turn the idler pully again and slide the belt over the alternator and release pressure from the idler pully. Visually inspect the path of the entire belt to make certain that it is properly installed before starting the engine. Don't let anyone stand to the side of the engine when starting it for the first time, since a mis-installed pully can be ripped apart quickly and relatively large pieces of reinforced rubber can really hurt when they hit you.
A few things, engine not running, loose belt, or seized pully on idler/tensioner or other acc.
Unbolt, slide off. Slide on new part, bolt back on.
Pin the top tension idler pully..take the front wheel off...the bottom idler pully is on an excentric...loosen same....belt goes slack.... put new belt on,set the excentric as tight as possible.. remove the pin in the top tension idler pully belt should be tight after doing this... happy days
the idler pully is the top center that that spins freely and is connected to the block.
